Masonry Repair and Strengthening Techniques: A Comprehensive Guide
Masonry Repair Techniques
Drilling and Plugging
The drilling and plugging method is suitable for repairing cracks that run in reasonably straight lines and are accessible at one end. This involves drilling along the length of the crack and grouting it to form a key using precast concrete or mortar plugs set in bitumen. The bitumen serves to break the bond between the plugs and the hole, preventing the plugs from cracking due to subsequent movement of the opening. For an enhanced seal, a second hole

Underpinning and Strengthening of Building Foundations
Methods for Underpinning Building Foundations
Pile and Beam Underpinning
Piles are installed beside the walls, and beams are inserted, both within the walls and through them, to join the tops of the piles. 
`Pynford’ Stool Method of Underpinning
This method can be used where the existing foundations are in a poor condition, and it enables the wall to be underpinned in a continuous run without the need for needles or shoring.

Types of TV Antenna Systems
Single-Family vs. Collective Buildings
TV antenna systems cater to two primary types of structures: single-family houses and collective buildings (buildings with multiple users).
Components of a TV Antenna System
Header Equipment
The header equipment receives signals from sensors and systems, ensuring their proper distribution to users. It houses all active components of the installation and is typically located near the sensor signals within the building.

1. Operations for Installation and Electricity Appropriation
During installation or when electricity is appropriated, the following operations should be performed:
- Open and visibly cut all sources of food.
- Block or lock equipment in the open position, if possible, by cutting.
2. Five Rules for Prevention and Protection During Work Without Tension
- Open cut all visible sources of tension: Use switches and disconnectors to ensure that they cannot be closed
